For a graph G on n … Undirected Graph. The undirected graph is also referred to as the bidirectional. It is a set of objects (also called vertices or nodes), which are connected together. Here the edges will be bidirectional. The two nodes are connected with a line, and this line is known as an edge. The undirected graph will be represented as G = (N, E). Yes. If you have a complete graph, the simplest algorithm is to enumerate all triangles and check whether each one satisfies the inequality. In practice, this will also likely be the best solution unless your graphs are very large and you need the absolute best possible performance. To construct an undirected graph using only the upper or lower triangle of the adjacency matrix, use graph (A,'upper') or graph (A,'lower') . When you use digraph to create a directed graph, the adjacency matrix does not need to be symmetric.
